I've got a problem and was hoping to find some advice here.
I have a Dell T5400 that has Vista x32 running and I wanted to upgrade to Windows 7 x64 to make use of increased RAM.
First I tried to do a clean install of Windows 7 from DVD. This did not work as I got the missing cd/dvd driver
error when trying to get through the installation.
So I've tried to make a bootable USB but whenever I get to the step when I run the bootsect.exe it says access denied.
I was pretty sure the DVD is working so I installed Windows 7 from within the Vista OS onto a separate HDD. No problems whatsoever.
I can now decide to use either Vista or Windows 7 when I boot up. Both work.
However Windows 7 is now on F: and Vista still on C:
I removed the Vista HDD to see if I can get just Windows 7 working but it comes up with the message that Bootmgr is missing so cant access Windows 7 alone.
I tried using the DVD to repair the install. It does recognize the Windows 7 but it didnt fix the bootmgr problem.
I couldn't find any drivers
for Windows 7 for the T5400 on the dell website either, only Vista.
So now I'm not sure where to best go from here.
I have 3 HDDs in the computer and I only really want/need one OS.
Ideally I wanted to use the 160gb WD Raptor for the OS/Apps and then use the 2 1TB Hitachi in Raid 1.
The Windows 7 installation is on the newly formatted WD Raptor whereas Vista is on one of the 2 Hitachi in a big partition. So thats not overly convenient for me.
What would be the best way for me to get either a new clean install in the above mentioned format or to fix up the existing working Windows 7? Any advice is appreciated
